ments such as lend themselves adaptable in prof viding desired walking traction on slippery and icy surfaces. More specifically, the invention comprises, a

malleable plate with detachable steel or equiv-- alent calks, the plate being provided with marginal anchoring and retention lugs, these having lateral spurs to be embedded in the heel for maintaining the attachment securely in place. Another object of the invention is to provide a simple and expedient heel attachment which'is suitably applicable to leather shoes with rubber lifts, but is especially appropriate for usefon waterproof boots having all rubber heelsQfthe attachment plate being provided with the aforementioned superequipped retention lugs which anchor themselves and obviate the necessityjof preparing special holes, there being sufficient adaptability present to insure full cushioning properties of the heel notwithstanding the presence of the attachment thereon.

The invention, as is obvious, is characterized by the utmost simplicity in construction land adaptability to the purposes intended, is reliable, easy to apply and remove and otherwise aptly fitted for suitably recognized utility.

Other features and advantages will become more readily apparent from the following .description and the accompanying illustrative drawing. In the drawing, wherein like numerals are employed to designate like parts throughout "the same: Figure l is a side elevational view of a" boot with an anti-skid attachment, constructed in accordance with this invention, in use on the noted by the numeral 5. It is characterized ncipally by a malleable or equivalent plate 6. ;Ifhis is of an area and shape to conform to an" fit against the underside of the 'conventio H on the boot B as seen in Figure 1. By erence the plate is provided, inward of its marginal limits with screw-threaded holes,; these to accommodate the screw-threaded shanks 1 on the pointed or conical steel calks 8. Other types of calks may be used. The outer marginal edge portions of the plate are provided with outstanding bendable lug-like extensions 9, these terminating in laterally directed anchoring and retention spurs 10. In practice, the plate is placed against the bottom of theheel and the lugs are bent up and around the marginal edge portions of the heel and the spurs in are driven, by hammer or the like into the leather of the heel for anchorage purposes. As a general proposition, if the heel includes a rubber lift R (as seen in Figure 1) the anchoring and retention lugs are preferably of a length to extend above the height or thickness of the lift whereby to embed the spurs into the leather only.

As I have stated before I desire to stress the provision of a non-skid device that can be attached to the heel of watertight boot or pac without the necessity of making holes through same for the purpose of inserting rivets or other fastening devices; also that my method of attaching heel plates retains at least the major part of resiliency afforded the wearer of such footwear as it is adapted to.

It is believed that an attachment of this type fulfills the requirements of such devices, and due, to its simplicity, an elaborate description is hardly necessary.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawing. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and arrangement of details coming within the field of inventionclaimed may be resorted to in actual practice, if desired.

Having described the invention, what is claimed as new is:

tact engagement with the heel of a'shoe and ter-,

minating in laterally bent pointed tongues extending inwardly from the upwardly bent tongues and adapted to be embedded in a heel above a rubber lift, and a multiplicity of calks having threaded shanks screwed into threaded openings formed in the body portion of the plate inwardly of the marginal edge thereof and removably mounting the calks against the underface of the plate in depending relation thereto.
